Description

Technical Field

[0001] This utility model relates to the technical field of steel coil winding machines, specifically a hydraulic stainless steel coil winding machine. Background Technology

[0002] Currently, a steel coil winding machine is a type of mechanical equipment specifically designed to wind steel plates into coils.

[0003] In the field of steel coil winding technology, with the expanding application range of stainless steel coils, the performance requirements for winding machines are also increasing. Traditional steel coil winding machines often struggle to meet all demands simultaneously when facing challenges such as high-precision winding, equipment durability, and operational safety. For example, during the winding process, due to the continuous changes in the thickness and width of the steel plate, traditional winding machines struggle to achieve precise guidance and compensation, leading to easy deviation or wrinkling of the steel plate during winding, affecting the winding quality. Furthermore, the protective pressure blocks and hydraulic protection blocks of traditional winding machines have simple structures and limited buffering effects, making it difficult to effectively absorb the enormous impact energy generated by the steel plate during high-speed winding or emergency braking, easily leading to damage to the steel plate edges, increased equipment vibration, or even malfunction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A hydraulic stainless steel coil winding machine includes a coiler 1, and two symmetrically arranged guides 2 are installed on one side of the coiler 1, characterized in that;

[0024] The plate roller 1 consists of an axially arranged take-up shaft 13 and a guide roller 21. The take-up shaft 13 is used for taking up the plate, and the guide roller 21 is used for guiding the take-up and untake-up of the steel plate.

[0025] The guide 2 consists of a guide roller 21, a protective pressure block 22, and a hydraulic protection block 23. The guide roller 21 is used to assist the movement of the coil, the protective pressure block 22 is used to protect the contact between the coil and the guide 2, and the hydraulic protection block 23 is used for compensation of the up and down sliding of the guide 2.

[0026] Specifically, a hydraulic stainless steel coil winding machine includes a coiler 1 and two symmetrically arranged guides 2. The coiler 1 is the core component of the equipment, consisting of an axially arranged winding shaft 13 and guide rollers 21. The winding shaft 13 is responsible for winding the coil, and its surface is specially treated to improve wear resistance. The guide rollers 21 are used to guide the coil's winding and unwinding, ensuring that the coil can move smoothly during the winding process. The guides 2 are installed on one side of the coiler 1 and consist of guide rollers 21, protective pressure blocks 22, and hydraulic protective blocks 23. The guide rollers 21 assist in the movement of the coil, and the protective pressure blocks 22 are used to protect the contact part between the coil and the guides 2, preventing damage due to friction or impact. The hydraulic protective blocks 23 are an important component of the guides 2, enabling the guides 2 to compensate for vertical sliding to accommodate coils of different thicknesses.

[0027] In this embodiment, the take-up auxiliary shaft 121 and the guide roller 21 are rotatably installed inside the plate winder 1 with their vertical axial distribution. One end of the take-up auxiliary shaft 121 is connected to a coaxially arranged rotating motor 12 via a coupling. A drive gear 122 is sleeved on the outer circumferential surface of the take-up auxiliary shaft 121. Two symmetrically arranged follower gears 131 and a take-up disc 132 are respectively sleeved on the outer circumferential surface of the take-up shaft 13. The drive gear 122 and the follower gear 131 mesh with each other.

[0028] Specifically, based on Embodiment 1, the transmission system of the winding machine has been optimized. The winding auxiliary shaft 121 and guide roller 21 are axially distributed and installed inside the winding unit 1. A coaxially mounted rotary motor 12 is connected to one end of the winding auxiliary shaft 121 via a coupling, providing power for the winding process. A drive gear 122 is fitted onto the outer circumference of the winding auxiliary shaft 121, while two symmetrically arranged follower gears 131 and a winding disc 132 are fitted onto the outer circumference of the winding shaft 13. The drive gear 122 and follower gear 131 mesh with each other, realizing power transmission. When the rotary motor 12 starts, it transmits power to the winding auxiliary shaft 121 via the coupling, which in turn drives the winding shaft 13 to rotate through the gear transmission system, achieving smooth winding of the stainless steel coil.

[0029] In this embodiment, the guide rollers 21 are rotated and installed inside the guide 2 in two symmetrical arrays at equal intervals.

[0030] Specifically, the structure of the guide 2 has been improved. The guide rollers 21 are rotatably installed inside the guide 2 in two symmetrical arrays and equidistant distributions. Each set of guide rollers 21 contains multiple cylindrical rollers. These rollers form a double-layer guide channel, which can guide the steel plate smoothly into the coiling station. The surface of the guide rollers 21 is covered with an elastic layer to reduce the damage to the steel plate caused by friction during movement. In addition, the arrangement of the guide rollers 21 can be adjusted according to actual needs to adapt to steel plates of different specifications and materials.

[0031] In this embodiment, the protective pressure blocks 22 are slidably assembled on one side of the guide 2 in a symmetrical arrangement, and two symmetrically arranged springs 221 are installed on the axial and radial sides of the protective pressure blocks 22 respectively.

[0032] In this embodiment, a damper 222 is mounted on the spring 221.

[0033] Specifically, the structure of the protective pressure block 22 has been optimized. The protective pressure blocks 22 are slidably mounted in pairs on one side of the guide 2. They are connected to the guide 2 via springs 221 and dampers 222, forming a buffer system. When the stainless steel coil experiences offset or impact during winding, the protective pressure blocks 22 can absorb the impact energy through the combined action of the springs 221 and dampers 222, preventing mechanical damage to the coil edges due to excessive pressure. Simultaneously, the sliding assembly of the protective pressure blocks 22 allows them to adapt to coils of different thicknesses and widths, improving the equipment's versatility.

[0034] In this embodiment, the hydraulic protection block 23 is installed on one side of the guide 2, and two symmetrically arranged hydraulic shafts 231 are installed on both sides of the hydraulic protector. One end of the two hydraulic shafts 231 on the same side is connected to a hydraulic oil tank 232.

[0035] Specifically, the structures of the hydraulic protection block 23 and the hydraulic shaft 231 have been optimized. The hydraulic protection block 23 is installed on one side of the guide 2 and integrates a hydraulic system controlled by a proportional servo valve. The hydraulic shaft 231 is symmetrically arranged on both sides of the hydraulic protection block 23 and connected to the hydraulic oil tank 232 via hydraulic oil circuits. When the thickness of the stainless steel coil changes, the displacement sensor can detect the position deviation of the guide 2 and transmit the signal to the PLC controller. The PLC controller outputs corresponding control commands based on the received signal, driving the proportional servo valve to adjust the extension and retraction of the hydraulic shaft 231, thereby enabling the guide 2 to track the position change of the coil in real time and perform corresponding slip compensation. In addition, the hydraulic system is also equipped with safety devices such as an overflow valve and an accumulator to ensure that the equipment can be safely shut down in an emergency.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
